• Not really, I'm measuring the low frequency response of a speaker system (15Hz to 100Hz). But I don't want to drive it below 15Hz. With my HP3562, I'll typically set it to trigger on the signal so its always centered in the window. I was wondering about windowing a signal that is delayed (microphone a fair distance away…

• That worked! Is there a way to limit the frequency response of the when using the excitation tab? If I use the signal generator, should the swept sine duration be equal to the FFT block size? Without a triggering option in the Dual FFT, how is the signal positioned in the acquisition window? Off topic, how do I delete data…

• Thanks, I'll give it a shot! Is there a way (maybe using the MIDI setup) to port the audio out to the audio in as well, or do you always need to put a cable between the two as a reference?
